Ask Vivaldi For Suggestions

Is this feature supposed to work right now like in Chrome? Because for me it's not. If I copy paste a paragraph from the net in both the browser in a text box... Vivaldi would mark tons more words as spelling mistakes compared to Chrome because Chrome is using Google Search spell checker while Vivaldi is probably using a static dictionary. If Google does allow using their spellchecker engine in third party browsers, it would be great if Vivaldi can incorporate that because the static dictionary is just not good enough for current times where tons of company names are marked as incorrect because they are not dictionary words.
